Back out previous commit; i.e., turn hyperthreading back on by default.
Newer Intel processors have better hyperthreading implementations than
the original ones, and FreeBSD's SMP and scheduler code has greatly
improved between 6.x and 7.x; so hyperthreading now provides a
non-trivial performance win.
Note that security issues involving shared caches and other
microarchitectural features (e.g., dynamic branch prediction tables)
still exist; consequently, it is recommended that hyperthreading be
turned off on systems with untrusted local users. This can be
performed by setting machdep.hyperthreading_allowed=0 in
/boot/loader.conf.
Hyperthreading will continue to be disabled by default on FreeBSD 6.x.

Merge nfs_vnops.c:1.277 from HEAD to RELENG_7:
Remove hacks from the NFSv2/3 client intended to handle a lack of a
server-side RPC retranmission cache for non-idempotent operations: these
hacks substituted 0 (success) for the expected EEXIST in the event that
a target name already existed for LINK, SYMLINK, and MKDIR operations,
under the assumption that EEXIST represented a second application of the
original RPC rather than a true failure.
Background: certain NFS operations (in this case, LINK, SYMLINK, and
MKDIR) are not idempotent, as they leave behind persisting state on the
server that prevents them from being replayed without an error;if an UDP
RPC reply is lost leading to a retransmission by theclient, the second
reply will return EEXIST rather than success, asthe new object has
already been created. The NFS client previouslysilently mapped the
EEXIST return into success to paper over thisproblem.
However, in all modern NFS server implementations, a reply cache is kept
in order to retransmit the original reply to a retransmitted request,
rather than performing the operation a second time, allowing this hack
to be avoided. This allows link()-based filelocking over NFS to operate
correctly, as an application requestingthe creation of a new link for a
file to tell if it succeededatomically or not.
Other NFS clients, including Solaris and Linux, generally follow this
behavior for the same reasons. Most clients also now default to TCP,
which also helps avoid the issue of retransmitted but non-idempotent
requests in most cases.

Let sunkbd(4) emulate an AT keyboard by default.
This has the following benefits:
- allows to use the AT keyboard maps in share/syscons/keymaps with

- allows to use kbdmux(4) with sunkbd(4),
- allows Sun RS232 keyboards to be configured and used the same
way as Sun USB keyboards driven by ukbd(4) (which also does AT
keyboard emulation) with X.Org, putting an end to the problem
of native support for the former in X.Org being broken over and

MFC MFp4: Several fixes to tmpfs which makes it to survive from pho@'s
strees2 suite, to quote his letter, this change:
1. It removes the tn_lookup_dirent stuff. I think this cannot be fixed,
because nothing protects vnode/tmpfs node between lookup is done, and
actual operation is performed, in the case the vnode lock is dropped.
At least, this is the case with the from vnode for rename.
For now, we do the linear lookup in the parent node. This has its own
drawbacks. Not mentioning speed (that could be fixed by using hash), the
real problem is the situation where several hardlinks exist in the dvp.
But, I think this is fixable.
2. The patch restores the VV_ROOT flag on the root vnode after it became
reclaimed and allocated again. This fixes MPASS assertion at the start
of the tmpfs_lookup() reported by many.

MFC 1.193:
The kernel uses two ways to write data on a pipe:
o buffered write, for chunks smaller than PIPE_MINDIRECT bytes
o direct write, for everything else
A call to writev(2) may receive struct iov of various size and the
kernel may have to switch from one solution to the other. Before doing
this, it must wake reader processes and any select/poll/kqueue up.
This commit fixes a bug where select/poll/kqueue are not triggered
when switching from buffered write to direct write. It adds calls to
pipeselwakeup().
